List files in a share using HSTK
AI agents call list_files to retrieve information from Hammerspace Storage Management MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and displays file information from a Hammerspace storage share. It performs no modifications, deletions, or execution of code. While it may expose file paths and metadata that could inform subsequent malicious actions, the tool itself is purely informational with minimal blast radius. Confidence is high because the name and description unambiguously indicate a read-only list operation.
From the tool's definition Tool name 'list_files' and description 'List files in a share' indicate a retrieval operation with no side effects. The verb 'list' is a canonical read operation that queries file metadata without modification.

List files in a share using HSTK. It is categorised as a Read tool in the Hammerspace Storage Management MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Hammerspace Storage Management MCP Server MCP server in PolicyLayer and add a rule for list_files: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Hammerspace Storage Management MCP Server. Nothing to install.
list_files is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the list_files rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for list_files. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
list_files is provided by the Hammerspace Storage Management MCP Server MCP server (mbloomhammerspace/mcp-1.5-main). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
